Lantac Enhanced Bolt Carrier Group, .308/7.62 Black Nitride

The Lantac USA Enhanced bolt carrier group (brand part no. 01-UP-762-NIT-EBCG) is built for .308 Winchester / 7.62 NATO AR10-pattern rifles, giving builders a durable, reliable carrier for the large-frame platform. Finished in black nitride, it is designed as an upgrade over a standard mil-spec carrier group, focused on smoother cycling and long-term wear resistance in a caliber that runs at higher pressures than a 5.56 build. Each unit ships one to a box, ready to drop into a compatible AR10 upper for a straightforward internals refresh or a new build.
